WILLIAM W. VANDERBILT, or NEW YORK, N. Y.

Letters Patent No. 491,796, dated June 22, 1869.

VENTILATOR FOR SHIPS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, W1LL1AM W. VANDERBILT, of N ew York, in the county of New York, and State of New York, have invented a new and useful Method ofVentilatng Vessels, particularly adapted for cabins and state-rooms; and l hereby declare the following to be a full, clear, and exact description of the same.

The object-of my invention is to place within the power and under the control of passengers, a simple and efficient arrangement to ventilate their apartments under all conditions of weather; that is to say, to provide for a steady iniiux of pure atmospheric air, and for the discharge of air which is vitiated by respiration, combustion, or other causes.

.The common windsail and similar devices for accomplishing this purpose, simply1 displace the noxious vapors, by mixing pure air with them, and in consequence thereof, only ventilate that part of the vessel in which they are situated.

Side-light openings simply ventilate the apartments in which they open, and cannot be used in stormy weather.

My invention consists essentially in forming a ven` tilator ofa space between the hurricane-deck and the ceilings of the state-rooms and cabins.

I place, in the ceiling of each state-room, two registers, with adjustable vanes, under the control of the occupant of the room, the Yanes so' arranged as to point in opposite directions, so that the air, in its passage athwartships, will be deflected into the room by the vanes ot' one register, and its passage overthe vnnes of the other register will so rarefy the air in the room as to cause an upward current, serving to exhaust the room of foul air, thus keeping up a circulation as long as desirable. I

1n the accompanying drawings, like letters refer to like parts.

Figure 1, plate 1, is an Aathwartship-section of the vessel through the state-rooms;

Figure 2 is a top view, showing the registers and partitions y Figure 3 is a side View; and

Figure 4 is a side view of the registers and the rod F, which operates the register to ventilate the lower vstate-room B.

In the ceiling of the upper state-room A, are two registers, O, opening into the ,athwartship-passages H, between the beams of the deck.

The registers, figs. 2 and 4, consist of light frames of brass or other suitable material, with movable vanes of the same material.

The vaues are connected with each other, and with handles, and in the lower state-room, with the rod F.

These vanes can be inclined, at will, iu opposite directions, or entirely closed.

The interior of the lower state-room B is connected with the space H, by means of the conduits or tubes, E, which have each a register in the upper end, adjusted by the rod F, so that the occupant ofthe lower stateroom has a means of ventilation entirelyunder his cont-rol. I claim as new and useful, and desire to secure by Letters Patentl The partitioned passages H H open at their ends, and situated between the ceilings of the upper stateroolus and the hurricane-deck., in combination with the registers C and conduits E, all constructed, arranged, and operated in the manner and for the purpose set forth.
